MOLD FOR Posrrs.

Specification of Letters Patent. 'P'dtg'h'te d 1 910.

Application filed September 4, 1909. Serial No. 516,236.

T 0 all whom it may concern:

Be it known that I, VILLIAM T. lllCKS, a

citizen of the United 5tates,-'residing at:

Bloomington, in the county of Monroe and State of Indiana, have inventedcertain new and useful Improvements in Molds for Posts, of which thefollowing is a specification.-

My invention relates to an improvement in molds or formers for moldingor forming a post or column from concrete, Portland cement, shale, orclay of the form shown in an application filed by me of even date herewith, Serial Number 516,235 and it has for its object the production ofa machine of this character in which such posts or columns may beexpeditiously and economically constructed, and the material from iwhich the post is built up is molded or; formed by mechanical meansrequiringxthe i tion of metal to the depth of the out, the

minimum of manual handling.

'ith these ends in view my invention con sists in certa n constructionsand arrangements of parts hereinafter fully described and pointed out inthe appended claims.

In the accompanying drawing illustrating my invention and. in which likenumerals designate the same parts wherever they occur, Figure 1 is acentral longitudinal section. Fig. 2' is a section taken on line 2, .5of Fig. .l and Fig. Z'l-is a fragmentary perspective view of the lowerend of the rotating packer. l designates a supporting table which, asshown, is provided with an opening i"), and

(3 is a pair of journal boxes mounted on op posite sides of the openingin the table, and

T are a pair of trunnions extending outwardly from opposite sides of thetube 8 which forms the mold. These ti'unnions 7 are mounted in thejournal boxes 6, so that the mold tube=can be swung in a vertical orhorizontal position.

The tube 8 is slightly tapered from its upper to its lower end, and atits upper end the tube is flared, as shown at 9, to facilitate thefilling of the mold. The lower end is closed by a cap 10 which,preferably and as shown, is screw threaded on the end of the tube. .\tthe lower end of the tube I provide a. concaved dish 11. which operatesto give the proper shape to the upper end of the completed post, saiddisk having a shaft 12 projecting from the rear face thereof, whichshaft extends through a central opening .in the head it), and on itsother end, which is exterior thelt ube; is "proruled with a head 13, "Byforcing thehead 13 inward thepost, after the same has been molded, canbe loosened fro nthe'tiibe, "so

that it may be readily removed,

l t is a vertical bearing which in'jline with the axis of thc'inoldtube'w ithe tube is vertical, as shown in Fig. '1. lntlli s hearing isjournaled a shaft 15, said shaft having a drive pulley l6 splinedtot-lie shaft, whereby the shaft can ,nioi'fe vertically through thebearing and the drive pulley. The shaft at its lower portion is providedwith a helical web or screw l7,'s a1d screw being'tapered to correspondto'the t'apr of the mold tube and is of a size to fit loose in the tube.lit the termination of the s an l I secure a disk 18 having openings 19fprmed therein by making in the periphery of the disk and turnitfgnp'tlie p'o'rturncd up portion 20 being preferably turned 'up at anangle, and the slits being so made in the disk that the turned up portions 20 will operate to force the material through the slits in theplate and then ride over the materialto pack the same down.

Preferably and as shown the tube 8 is not circula r but is provided witha flattened side it which extends from thesmaller. end of the moldanyil'esired distance, in order that the post molded by the machine willhave a Hat face for the purposes fully set forth-in my companionapplication above referred to. I

From the foregoing description of the construction of my apparatus itwill be seen that when the tube is placed in vertical position with itslarger end upward the shaft 15 can he slid down into the tribe untilthedislt 11S reaches the ejector disk 11. Thein'ol te'fial from whichthe post is to be m'adis now "fodintoth'e mold and thesliaft 143rotateddna direction to cause the screw tov force the materialdownwardly and out.- wardly. The material will be radually forcedthrough the slots 19 in the c islilsby theturned up wings its theoperation is continued the screw will be gradually forced out of thetube until finally the'tilbe has been completely filled with thematerial from which the post is made, By using the constructiondescribed all parts of the post will be'even'ly and expeditiouslypacked, so that when the tube has been completely filled the shaft ismoved up to be I now be turned on its trunnions either upside out of theway, and the tube can down or into a horizontal position, and by meansof the'ejector 11 the molded post can vhe forced from the tube.

-What Iclaim as'new and desire to secure by Letters Patent is opening,and extending 1 at disk, one of said cated'on opposite sides of the opand the-like, the combination with a tablehavingan opening therein,journal boxes 10- ening, a mold tube provided with trunnions, saidtrunnions being mounted. in the journal boxes, a shaft, a helical web onthe shaft, said shaft being' movable. into said tube, a diskmountedon'the end of the shaft at the end f the helical web, said diskbeing provided with openings, wings extending up from the Wings beinglocated at one edgeof each opening, and extending at an "angle-to thedisk, and means for rotating the .shaft.'

3. In a machine for molding fence posts and the like, the combinationwith the mold tube, of a shaft having a; helical web on one end thereof,said shaft being movable longitudinallyin the said tube, a disk mountedon the end ofthe shaft-at the end of the helical web, said disk beingprovided with openings, wings extendin up from the disk, one of saidwings being%ocated at one edge of each opening, and extending at anangle to the disk, means for rotating the shaft a concaved ejector diskmounted in the an of the tube and having a stem pro ecting outside ofthe tube.

at. In a machine for molding fence posts and the like, the combinationwith the mold tube, of a shaft having a helical web on one end thereof,said shaft being movable longitudinally in the said tube, a disk mountedon the end of the shaft at the end of the helical Web, said disk beingprovided with openings, wings extending up from the disk, one of saidWing's being located at one edge of each 'dpening, and extending at anangle to the disk, and means for rotating the shaft, a portion of oneside of said tube being flattened.

In testimony whereof I affix my signature in presence of two witnesses.
